PTZ often does not stop, when using App or WebUI

Hi. I am doing some testing on a new system here.

What I have found is that the mobile app and PTZ does not work as intended. If i hit the left arrow it will get highlighted and stay highlighted and the camera moves all the way in the correct direction. I can click beside the buttons to un-highlight it, but the camera moves all the way. No way to stop it where I want. Same for every direction. All the way or nothing.

From remote PC with web-browser or Netcam Studio Client everything works as it should.

But! My plan was to use this mobile client.

Everything is latest version and updated.

Camera info here:

Phone is Android
Samsung A7 2017

Please fix this!
